The revolutionary Genius 8900 electric toothbrush features a round brush head inspired by dental instruments, designed to surround each tooth with oscillating, rotating, and pulsating cleaning technology to remove up to 100% more plaque than a traditional manual toothbrush. It is designed to help you brush as your dentist recommends. The toothbrush can be paired with the Oral-B smartphone app via Bluetooth to provide you with personalized real-time feedback, including assistance in adhering to the recommended brushing time of 2 minutes, a triple pressure control to protect your gums from excessive pressure, and advanced position detection technology to ensure you never miss a spot. The 360º SmartRing with LED lights allows you to personalize your brushing experience. The design and technology of Oral-B toothbrushes come from Braun. Oral-B is the brand that introduced sonic technology in 1963 and oscillating-rotating technology in 1998. Oral-B remains the number one toothbrush brand most recommended and used by dentists worldwide. This package includes 2 handles.
